Home > Marking > Castration

Male lambs, unless marked for slaughter prior to puberty, will usually be castrated. Castration should be performed on lambs as early as management practices will allow, preferably before 12 weeks of age. Animals older than six months require anaesthetic.

Acceptable methods of castrating male lambs without anaesthesia are:

  • Cutting. The lambs should be properly restrained and the knife must be kept clean and sharp.
  • Rubber rings applied according to the manufacturer’s recommendations.
